AB  - OBJECTIVE: To analyze the clinical agreement between the conventional 
      intermittent bolus thermodilution (TD) technique and a new arterial pressure 
      waveform analysis (APCO) technique (FloTrac; Edward Lifesciences, Irvine, CA) for 
      cardiac output (CO) estimation. DESIGN: Prospective observational clinical study. 
      SETTING: Cardiac surgery operating room of a tertiary care cardiac center. 
      PARTICIPANTS: Twelve patients undergoing elective off-pump coronary artery bypass 
      (OPCAB) surgery. MEASUREMENTS AND MAIN RESULTS: CO was determined by 2 different 
      methods: TD and APCO at 8 time points (preinduction, postinduction, 
      poststernotomy, left internal mammary artery to left anterior descending artery 
      anastomosis, left [obtuse marginal/diagonal] anastomosis, right [right 
      coronary/posterior descending coronary artery] anastomosis, postprotamine 
      administration, and poststernal closure) in 12 patients undergoing elective OPCAB 
      surgery. The mean bias and limits of agreement (2 standard deviations) expressed 
      in liters per minute at respective points of measurement were -0.54 +/- 1.12, 
      -0.37 +/- 1.0, -0.42 +/- 1.50, -0.25 +/- 1.18, -0.31 + 1.28, +/-0.41 +/- 1.0, 
      0.06 +/- 1.50, and 0.09 +/- 1.40. CONCLUSION: Good agreement was found between 
      the CO values obtained by the APCO and TD techniques throughout the 
      intraoperative period including the period of coronary artery graft surgery.
